    Abstract: Generally, the present disclosure is related to various techniques that may be used for forming metallization systems in a highly efficient manner by filling via openings and trenches in a common fill process, while reducing negative effects during the patterning of the via opening and the trenches. One illustrative method disclosed herein includes, among other things, forming a via opening in a first dielectric material of a metallization layer of a semiconductor device. Moreover, a second dielectric material is formed above the first dielectric material, wherein the second dielectric material fills the via opening. Furthermore, the method also includes forming a trench in the second dielectric material so as to connect to the via opening, and filling the trench and the via opening with a metal in a common fill process.
